Nothing projects on the screen. What should I do?

• Try the following:
  • Press the Source Search button on the projector or the Search button or the specific source button on the remote control to select the correct input source. Allow a few seconds for the projector to sync up after pressing the button.
  • Check that the  Power light is green, not flashing, and the A/V mute slide (lens cover) is open.
  • Press the A/V Mute button on the remote control to see if the picture was turned off temporarily.
  • If the projector doesn't turn on, the Control Panel Lock function may be enabled. Press and hold the Enter button on the projector for 7 seconds to release the lock.
  • The projector may be in standby or sleep mode. If the  Power light is orange, press the  Power button to turn on the projector.
  • If you've connected a computer, it may also be in sleep mode or displaying a black screen saver. Try pressing a key on the computer.
  • If the power was switched off and then on again, wait until the  Power light stops flashing and remains orange. Then press the  Power button again.
  • Check the Video Signal or Input Signal setting in the Signal menu to make sure it is correct for the selected source. See Adjusting Signal Settings.
  • Messages may have been turned off in the Display setting of the Extended menu. See Customizing Power and Operation.
  • Adjust the Brightness setting in the Image menu (see Adjusting the Image) or select High for the Brightness Control setting in the Settings menu (see Customizing Projector Features).
  • If you are projecting from a DVD player or other video source, make sure you turn it on and press its Play button.
  • Make sure your cable(s) are connected correctly. See Setting up the Projector.
  • If you're using a device connected to the USB port, make sure the port is set up for USB display in the projector menu and that you are running Windows XP or Vista.
  • If you've connected a laptop computer, make sure it's set to display on an external monitor.
  If you're using a PC notebook:
  • Press the function key that lets you display on an external monitor. It's often labeled with an icon such as , but it may also be labeled CRT/LCD. You may have to hold down the Fn key while pressing it. Check your laptop's manual or online help.
    
    On most systems, the key lets you toggle between the LCD screen and the projector, or display on both at the same time. Allow a few seconds for the projector to sync up after pressing it.
    
    If that doesn't work, press the ? Help button on the projector for a list of laptop brand-specific button combinations you can press to switch to an external display.
  • If the function key doesn't let you display simultaneously on both screens, you might need to use the Display utility in the Windows Control Panel to make sure that both the LCD screen and external monitor port are enabled. From the Windows Control Panel, open the Display utility. Click the Settings tab, then click Advanced. The method for adjusting the setting varies from computer to computer; you may need to click a Monitor tab, then make sure the external Monitor port is set as your primary display or enabled. See your computer manual or online help for details.
  If you're using Macintosh OS X:
  1. Make sure the projector is connected to your Macintosh.
  2. Select System Preferences from the Apple menu and click Displays.
  3. Click Detect Displays.
  4. To display the entire desktop on both your projector screen and LCD screen, click the Arrangement or Arrange tab. (If you don't see this tab, make sure it isn't hidden by another window.)
  5. Click Mirror Displays in the lower corner of the screen. One of the monitor icons automatically moves on top of the other.
